Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a multifunctional urinary catheter and a urinary catheter recovery device thereof. Background Art

[0002] A urinary catheter is a tube that is inserted into the bladder through the urethra to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) and can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an air bag near the tip of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine.

[0003] The existing urinary catheter generally has the functions of catheterization and bladder flushing. There is also a pipeline connected to the airbag inside the urinary catheter, which allows water to be flushed into the airbag to inflate the airbag, thereby effectively fixing the urinary catheter inside the bladder. The airbag itself has a certain elasticity, and the time for the urinary catheter to be left in the body varies according to the patient's condition. The urinary catheter is fixed inside the bladder for a long time. When it is necessary to drain the water and gas inside the airbag before removing the urinary catheter, the airbag will be in an expanded state and lose some elasticity, and it will be impossible to discharge all the gas and water inside. This will cause the volume of the airbag to increase, which will cause pain to the patient when removing the urinary catheter. It is necessary to use an external extraction device to completely extract the water and gas inside the airbag, which will increase the chance of infection for patients who frequently change urinary catheters. In addition, the urine bag corresponding to the urinary catheter also lacks a fixing effect with the urinary catheter, which is prone to problems such as loose connection and part of the urine flowing out along the urinary catheter when the urine bag is replaced.

[0004] Based on this, the present invention designs a multifunctional urinary catheter and a urinary catheter recovery device thereof to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a multifunctional urinary catheter and a urinary catheter recovery device thereof to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multifunctional urinary catheter, comprising a catheter, a first connector fixedly connected to the bottom of the catheter, an air bag fixedly connected to the top of the catheter, a flushing tube fixedly connected to one side of the catheter, a one-way valve arranged inside the flushing tube, a flushing pipe fixedly connected to the other side of the catheter, an inlet and outlet liquid channel opened inside the catheter, the first connector and the flushing tube are connected to the inlet and outlet liquid channel, a flushing channel is opened inside the catheter, one end of the flushing channel is connected to the air bag, and the other end of the flushing channel is connected to the flushing pipe, a drainage suction assembly is arranged on the flushing pipe, and the drainage suction assembly is used to completely suck out the air and moisture inside the air bag so as to facilitate the catheter to be pulled out of the urethra after use.

[0007] As a further solution of the present invention, the drainage and suction assembly includes a connecting column. A chute is provided inside the flushing water pipe. The diameter of the chute is larger than the diameter of the pipe orifice inside the flushing water pipe. The connecting column is slidably arranged inside the chute. A connecting frame is penetrated through the chute. A sealing block is fixedly connected to the top of the connecting frame. The sealing block can be hermetically connected to the connecting column. A baffle is fixedly connected to the bottom of the connecting frame. Clamping rings for fixing the position of the connecting frame on the connecting column are respectively and fixedly connected to the outer walls on both the upper and lower sides of the connecting frame. Connecting rods are respectively and fixedly connected to both sides of the bottom of the connecting column. Connecting grooves are respectively opened on both sides of the bottom of the flushing water pipe. A connecting sleeve is sleeved outside the flushing water pipe. The bottom of the connecting rod passes through the connecting groove and is fixedly connected to the connecting sleeve.

[0008] As a further solution of the present invention, a urine drainage and recovery device for a multi-functional urinary catheter includes a urine bag. A docking head is spirally connected to the top of the urine bag. A second connecting head is fixedly connected inside the docking head. The second connecting head can be inserted into the inside of the first connecting head. A second rubber sealing ring is arranged at the top of the second connecting head. The second rubber sealing ring is fixed inside the docking head. A first rubber sealing ring is fixedly connected inside the first connecting head. Card slots are respectively opened on both sides of the bottom of the catheter. A positioning and clamping assembly for buckling and connecting with the card slots is arranged on the docking head. The positioning and clamping assembly is used for fixedly connecting the catheter and the docking head.

[0009] As a further solution of the present invention, the positioning and clamping assembly includes a fixed seat. The fixed seat is fixed on one side of the top of the docking head. A swing rod is rotatably connected to the fixed seat. A conical block is arranged at the top of the swing rod. A pressing end is arranged at the bottom of the swing rod. A return spring for its reset is fixedly connected to one end of the pressing end.

[0010] As a further solution of the present invention, a shoulder strap is fixedly connected to one end of the urine bag. The shoulder strap is used for sleeving and fixing the position of the urine bag with an external support.

[0011] As a further solution of the present invention, the top of the liquid inlet and outlet channel is flared, and the outer wall of the catheter is a smooth wall.

[0012] As a further solution of the present invention, the outer wall of the connecting column is a smooth wall, and the connecting column can be hermetically attached to the inner wall of the chute.

[0013] As a further solution of the present invention, the airbag is made of elastic rubber material.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The present invention adopts a drainage and suction assembly. When the airbag is inflated with water and expands, it can seal the flushing tube, so that the air and clear water inside the airbag will not be squeezed out, keeping the airbag in a good sealed state. When draining the water and gas inside the airbag, it can completely suck out the water and gas inside the airbag, avoiding the problem that the insufficient discharge under the action of its own pressure causes the width of the airbag to still be wider than the catheter, resulting in inconvenience in removing it from the patient's body, and making it more convenient to use.

[0016] 2. The present invention adopts a urine drainage and recovery device. Through the rubber sealing ring on the recovery device, it cooperates with the rubber sealing ring at the bottom of the catheter. When not connected, both the bottom of the catheter and the urine bag are in a sealed state. In this way, when replacing the urine bag, after the first connector is pulled out from the inside of the docking head, the first connector and the urine bag become sealed again. In this way, the urine remaining in the catheter will not drip along the first connector, and the urine collected inside the urine bag will not flow out due to external extrusion, and the use effect is better.

Return spring. Detailed implementation mode

[0027] Please refer to Figure 1-8 , the present invention provides a technical solution: a multifunctional catheter, including a catheter 2, the bottom of the catheter 2 is fixedly connected with a first connector 5, the top of the catheter 2 is fixedly connected with an airbag 1, the airbag 1 is made of elastic rubber material, one side of the catheter 2 is fixedly connected with a flushing tube 3, a one-way valve is arranged inside the flushing tube 3, the other side of the catheter 2 is fixedly connected with a flushing water pipe 4, a liquid inlet and outlet channel 8 is opened inside the catheter 2, the first connector 5 and the flushing tube 3 are both connected to the liquid inlet and outlet channel 8, a flushing water channel 9 is opened inside the catheter 2, one end of the flushing water channel 9 is docked with the airbag 1, the other end of the flushing water channel 9 is docked with the flushing water pipe 4, a drainage and suction assembly is arranged on the flushing water pipe 4, and the drainage and suction assembly is used to completely suck out the air and moisture inside the airbag 1 so as to facilitate the removal of the catheter 2 from the urethra after use;

[0028] When the above solution is put into actual use, when using the catheter, insert the catheter 2 along the urethra into the patient's bladder, fill the airbag 1 with clean water along the flushing water channel 9 through the flushing water pipe 4, and the volume of the airbag 1 increases after flushing and is fixed at the interface between the bladder and the urethra, so as to fix the catheter 2 inside the patient's urethra. When the patient produces urine, the urine in the bladder can be discharged out of the body along the catheter 2. When internal care needs to be carried out on the patient, the medicine for flushing the bladder can be sent into the patient's body along the flushing tube 3 through the liquid inlet and outlet channel 8. Since a one-way valve is arranged inside the flushing tube 3, the urine will not enter the inside of the flushing tube 3 when it is discharged through the liquid inlet and outlet channel 8, ensuring that the flushing tube 3 will not be contaminated by urine. When the catheter 2 needs to be removed after use, first use the drainage and suction assembly on the flushing water pipe 4 to completely suck out the gas and moisture inside the airbag 1, so that the airbag 1 returns to the position where it fits with the catheter 2, and then the catheter 2 can be removed from the patient's body. The present invention adopts a drainage and suction assembly, which can completely suck out the moisture and gas inside the airbag 1, avoiding the problem that the airbag 1 is not discharged enough under its own pressure, resulting in the width of the airbag 1 still being wider than that of the catheter 2 and being inconvenient to be removed from the patient's body, and is more convenient to use.

[0029] As a further solution of the present invention, the drainage and suction assembly includes a connecting column 16. A chute 10 is formed inside the flushing water pipe 4. The caliber of the chute 10 is larger than the caliber of the pipe orifice inside the flushing water pipe 4. The connecting column 16 is slidably arranged inside the chute 10. A connecting frame 14 penetrates through the chute 10. A sealing block 13 is fixedly connected to the top of the connecting frame 14. The sealing block 13 can be hermetically connected to the connecting column 16. A baffle 17 is fixedly connected to the bottom of the connecting frame 14. Snap rings 15 for fixing the position of the connecting frame 14 on the connecting column 16 are respectively and fixedly connected to the outer walls on both the upper and lower sides of the connecting frame 14. Connecting rods 18 are respectively and fixedly connected to both sides of the bottom of the connecting column 16. Connecting grooves 11 are respectively formed on both sides of the bottom of the flushing water pipe 4. A connecting sleeve 12 is sleeved outside the flushing water pipe 4. The bottom of the connecting rod 18 passes through the connecting groove 11 and is fixedly connected to the connecting sleeve 12;

[0030] When the above solution is put into actual use, when filling the airbag 1 with water through the flushing water pipe 4, the initial state of the drainage and suction assembly is as Figure 5 shown. At this time, the clear water is sent into the airbag 1 through the unsealed connecting column 16. After the water filling is completed, pull the connecting sleeve 12, drive the connecting column 16 to slide upward through the connecting rod 18. When the top of the connecting frame 14 slides to the top of the chute 10, continue to push the connecting sleeve 12, then the connecting rod 18 will drive the connecting column 16 to slide upward relative to the connecting frame 14, so that the positions of the connecting frame 14 and the sealing block 13 are fixed, and the sealing block 13 gradually inserts into the inside of the connecting column 16 for sealing, that is, the entire flushing water pipe 4 is sealed, so that the water and gas inside the airbag 1 will not escape, and the airbag 1 will continuously expand, and then the catheter 2 can be fixed inside the urethra;

[0031] When it is necessary to remove the catheter 2 to exhaust the airbag 1, pull the connecting sleeve 12 downward. At this time, the connecting rod 18 will drive the connecting column 16 to slide downward. Due to the limiting effect of the snap ring 15 on the connecting column 16, the connecting frame 14 will slide downward together with the connecting column 16 until the bottom of the connecting frame 14 contacts the bottom wall of the chute 10. Continue to pull the connecting sleeve 12. At this time, the connecting column 16 slides downward relative to the connecting frame 14, so that the sealing block 13 disengages from the inside of the connecting column 16, and the seal is released. The water and gas inside the airbag 1 will be discharged. However, due to continuous expansion, the elasticity of the surface of the airbag 1 decreases and it cannot return to the position with the same width as the catheter 2. At this time, the connecting sleeve 12 can be pulled up and down repeatedly. When the connecting column 16 slides to the uppermost end, the inside of the flushing water pipe 4 is sealed. Pulling the connecting sleeve 12 downward can bring out the water and gas inside the airbag 1. When the connecting column 16 slides to the lowermost end, the connecting column 16 disengages from the seal with the snap ring 15 to bring out the gas and water inside the airbag 1. By repeatedly pulling the connecting sleeve 12, the gas and water inside the airbag 1 are completely discharged, and then the catheter 2 can be conveniently removed from the patient's body.

[0032] As a further solution of the present invention, a urine drainage and recovery device for a multi-functional urinary catheter includes a urine bag 20. A docking head 19 is spirally connected to the top of the urine bag 20. A second connector 23 is fixedly connected inside the docking head 19. The second connector 23 can be inserted into the inside of the first connector 5. A second rubber sealing ring 22 is arranged at the top of the second connector 23. The second rubber sealing ring 22 is fixed inside the docking head 19. A first rubber sealing ring 7 is fixedly connected inside the first connector 5. Card slots 6 are respectively formed on both sides of the bottom of the catheter 2. A positioning and clamping assembly for buckling with the card slots 6 is arranged on the docking head 19. The positioning and clamping assembly is used for fixedly connecting the catheter 2 and the docking head 19.

[0033] When the above solution is put into actual use, when using the urine drainage and recovery device, it is necessary to dock the first connector 5 at the bottom of the catheter 2 with the urine bag 20 for convenient urine collection. When using the urine bag 20, the urine bag 20 and the catheter 2 are fixed by the positioning and clamping assembly. The present invention adopts the positioning and clamping assembly, which can fixedly connect the urine bag 20 and the catheter 2, increase the firmness of the urine bag 20 during use, and will not easily fall off. When the first connector 5 is inserted into the docking head 19 at the top of the urine bag 20, the bottom of the first connector 5 contacts the second rubber sealing ring 22, and after squeezing the second rubber sealing ring 22 to open, it is sleeved outside the second connector 23. After the second connector 23 enters the first connector 5 and contacts the first rubber sealing ring 7, the first rubber sealing ring 7 is squeezed to open. When both the first rubber sealing ring 7 and the second rubber sealing ring 22 are opened, the sealing conditions at the bottom of the first connector 5 and inside the docking head 19 are both disconnected. At this time, the catheter 2 and the urine bag 20 can be connected and used. The purpose of doing this is that when the catheter 2 is not connected to the urine bag 20, both the catheter 2 and the urine bag 20 are in a sealed state respectively. In this way, when replacing the urine bag 20, after the first connector 5 is pulled out from the inside of the docking head 19, the first connector 5 and the urine bag 20 become sealed again. In this way, the urine remaining in the catheter 2 will not drip along the first connector 5, and the urine collected in the urine bag 20 will not flow out due to external force extrusion, and the use effect is better.

[0034] As a further solution of the present invention, the positioning and clamping assembly includes a fixed seat 26. The fixed seat 26 is fixed on one side of the top of the docking head 19. A swing rod 25 is rotatably connected to the fixed seat 26. A cone block 24 is arranged at the top of the swing rod 25. A pressing end 27 is arranged at the bottom of the swing rod 25. One end of the pressing end 27 is fixedly connected with a return spring 28 for its reset.

[0035] When the above solution is put into actual use, when docking the first connector 5 with the docking head 19, first press the pressing end 27 to make the swing rod 25 rotate around the fixed seat 26 to compress the return spring 28, so that the space at the top of the swing rod 25 becomes larger. After the first connector 5 is inserted into the docking head 19, release the pressing end 27. Under the elastic force of the return spring 28, the swing rod 25 rotates and resets. The conical block 24 at the top of the swing rod 25 will be inserted into the card slot 6 on the catheter 2, thereby fixing the catheter 2 to the urine bag 20. When the urine bag 20 needs to be replaced, press the pressing end 27 in the same way to make the conical block 24 slide out of the card slot 6 to pull out the catheter 2.

[0036] As a further solution of the present invention, one end of the urine bag 20 is fixedly connected with a shoulder strap 21, and the shoulder strap 21 is used to be sleeved with an external support to fix the position of the urine bag 20;

[0037] When the above solution is put into actual use, the urine bag 20 can be hung on the support object through the shoulder strap 21 to facilitate fixing the position of the urine bag 20.

[0038] As a further solution of the present invention, the top of the liquid inlet and outlet channel 8 is flared, and the outer wall of the catheter 2 is a smooth wall;

[0039] When the above solution is put into actual use, the flared liquid inlet and outlet channel 8 can achieve a better drainage effect and further facilitate the patient to urinate.

[0040] As a further solution of the present invention, the outer wall of the connecting column 16 is a smooth wall, and the connecting column 16 can be hermetically fitted with the inner wall of the chute 10;

[0041] When the above solution is put into actual use, the smooth connecting column 16 has a small friction force when sliding inside the chute 10, and the sealed connection between the connecting column 16 and the chute 10 can effectively prevent the clear water from flowing out.

[0042] Working principle: When using the urinary catheter, insert the catheter 2 along the urethra into the patient's bladder. When filling the airbag 1 with water through the flushing pipe 4, the initial state of the drainage and suction assembly is as Figure 5As shown in the figure, at this time, clear water is sent into the airbag 1 through the unsealed connecting column 16. After the water filling is completed, the connecting sleeve 12 is pulled, and the connecting column 16 is driven to slide upward through the connecting rod 18. When the top of the connecting frame 14 slides to the top of the chute 10, the connecting sleeve 12 is continuously pushed, then the connecting rod 18 will drive the connecting column 16 to slide upward relative to the connecting frame 14, so that the positions of the connecting frame 14 and the sealing block 13 are fixed, and the sealing block 13 gradually inserts into the inside of the connecting column 16 for sealing, that is, the entire flushing pipe 4 is sealed, so that the water and gas inside the airbag 1 will not run out, and the airbag 1 will continue to be in an inflated state, and the catheter 2 can be fixed inside the urethra. After the airbag 1 is filled with water, its volume increases and it is fixed at the interface between the bladder and the urethra, so as to fix the catheter 2 inside the patient's urethra. When the patient produces urine, the urine in the bladder can be discharged out of the body along the catheter 2. When internal care needs to be performed on the patient, the medicinal liquid for flushing the bladder can be sent into the patient's body along the flushing pipe 3 through the liquid inlet and outlet channel 8. Since a one-way valve is provided inside the flushing pipe 3, the urine will not enter the inside of the flushing pipe 3 when it is discharged through the liquid inlet and outlet channel 8, ensuring that the flushing pipe 3 will not be contaminated by urine;

[0043] When using the urinary catheter recovery device, the first connector 5 at the bottom of the catheter 2 needs to be docked with the urine bag 20 to facilitate urine collection. When using the urine bag 20, the urine bag 20 and the catheter 2 are fixed through the positioning and clamping assembly. The present invention adopts the positioning and clamping assembly, which can fixedly connect the urine bag 20 and the catheter 2, increase the firmness when using the urine bag 20, and will not fall off easily. When the first connector 5 is inserted into the docking head 19 at the top of the urine bag 20, the bottom of the first connector 5 contacts the second rubber sealing ring 22. After squeezing the second rubber sealing ring 22 to open, it is sleeved outside the second connector 23. After the second connector 23 enters the first connector 5 and contacts the first rubber sealing ring 7, the first rubber sealing ring 7 is squeezed to open. When both the first rubber sealing ring 7 and the second rubber sealing ring 22 are opened, the sealing conditions at the bottom of the first connector 5 and inside the docking head 19 are both disconnected. At this time, the catheter 2 and the urine bag 20 can be connected and used. The purpose of doing this is that when the catheter 2 is not connected to the urine bag 20, both the catheter 2 and the urine bag 20 are in a sealed state respectively. In this way, when replacing the urine bag 20, after the first connector 5 is pulled out from the inside of the docking head 19, the first connector 5 and the urine bag 20 become sealed again. In this way, the urine remaining inside the catheter 2 will not drip along the first connector 5, and the urine collected inside the urine bag 20 will not flow out due to external force extrusion;

[0044] When it is necessary to take out the catheter 2 to exhaust the airbag 1, pull down the connecting sleeve 12. At this time, the connecting rod 18 will drive the connecting column 16 to slide downward. Due to the limiting effect of the snap ring 15 on the connecting column 16, the connecting frame 14 will slide downward together with the connecting column 16. When the bottom of the connecting frame 14 contacts the bottom wall of the chute 10, continue to pull the connecting sleeve 12. At this time, the connecting column 16 slides downward relative to the connecting frame 14, so that the sealing block 13 disengages from the inside of the connecting column 16, and the seal is released. The moisture and gas inside the airbag 1 will be discharged. However, due to continuous swelling, the elasticity of the surface of the airbag 1 decreases and it cannot return to the position with the same width as the catheter 2. At this time, the connecting sleeve 12 can be repeatedly pulled up and down. When the connecting column 16 slides to the uppermost end, the inside of the flushing pipe 4 is sealed, and pulling down the connecting sleeve 12 can bring out the moisture and gas inside the airbag 1. When the connecting column 16 slides to the lowermost end, the connecting column 16 disengages from the seal with the snap ring 15 to bring out the gas and moisture inside the airbag 1. By repeatedly pulling the connecting sleeve 12, the gas and moisture inside the airbag 1 are completely discharged. When it is necessary to take out the catheter 2 after use, first use the drainage and suction assembly on the flushing pipe 4 to completely suck out the gas and moisture inside the airbag 1, so that the airbag 1 returns to the position fitting the catheter 2, and then the catheter 2 can be taken out from the patient's body.
